TDSQL 安装ansible报错，如下：http://www.cndba.cn/cndba/dave/article/4622http://www.cndba.cn/cndba/dave/article/4622http://www.cndba.cn/cndba/dave/article/4622

[dave@www.cndba.cn settings]# ls

[dave@www.cndba.cn settings]# python install_ansible.py
Traceback (most recent call last):
  File "install_ansible.py", line 11, in <module>

OSError: [Errno 2] No such file or directory: ''

[dave@www.cndba.cn settings]# cat install_ansible.py
#! /usr/bin/env python
# coding: utf-8

from py_modules import functions
import os
import shutil
import sys

os_version = functions.get_os_version()
work_dir = os.path.dirname(sys.argv[0])
os.chdir(work_dir)

msg_info = functions.colored('Ansible is install successful!', 'green')

if os_version == 1:
    os.system('rpm -ivh --force ansible/centos6/*')
    print msg_info
elif os_version == 2:
    os.system('yum install -y openssl openssl-devel')
    os.system('rpm -ivh --force ansible/centos7/*')
    print msg_info
else:
    print 'The OS type neither centos-6 nor centos-7, the program will be exit!'

shutil.copy('ansible.cfg', '/etc/ansible/ansible.cfg')

这里代码比较简单， 因为看到扩展名是py的所以加了python， 注意报错的11行获取地址的方式：sys.argv[0]。http://www.cndba.cn/cndba/dave/article/4622http://www.cndba.cn/cndba/dave/article/4622http://www.cndba.cn/cndba/dave/article/4622

所以我们这里直接执行，不加python。 如下：http://www.cndba.cn/cndba/dave/article/4622

[dave@www.cndba.cn settings]# pwd
/data/tdsql_full_install_ansible/settings
[dave@www.cndba.cn settings]# ls
ansible  ansible.cfg  install_ansible.py  py_modules

[dave@www.cndba.cn settings]#
[dave@www.cndba.cn settings]# ./install_ansible.py
-bash: ./install_ansible.py: Permission denied

这里提示权限不足，附加权限，安装成功：http://www.cndba.cn/cndba/dave/article/4622

[dave@www.cndba.cn settings]# chmod a+x install_ansible.py

[dave@www.cndba.cn settings]# ./install_ansible.py
